Rose plant named ‘Emily Carr’

ABSTRACT

A new and distinct variety of rose, distinguished by its deep red flowers, disease resistance and cold tolerance.

Latin name of the genus and species of the plant claimed: Rosa sp.

Variety denomination: ‘Emily Carr’.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rosenamed ‘Emily Carr’. The new rose ‘Emily Carr’ resulted from ahybridization programme and is a selection from a series of cross bymanual pollination. The series can be described as follows:

[(Lammert's selection×Morden Cardinette)×Morden Cardinette]×CuthbertGrant

The cultivar was created in Morden, Manitoba in 1982, Canada, andselection subsequently occurred at another location in Quebec, Canada in1998-1999.

The ‘Emily Carr’ rose plant variety of the present invention: a) isresistant to mildew, b) almost continuous flowering, with deep redflowers, c) the flowers are semi-double, d) the plant is a large shrubwith an upright growth habit, and d) shows cold tolerance.

Asexual reproduction of this new variety shows that the foregoing andother characteristics come true to form, are firmly fixed, and areestablished and transmitted through succeeding propagations. The instantcultivar was asexually reproduced by softwood cutting in Morden,Manitoba, Canada. Cutting size can be variable but new shoots(soft-wood) taken 3-5 nodes in length root well under intermittent mist,common in the industry. Root hormone (IBA) can speed root development.

The colours of an illustration of this type may vary with lighting andother conditions under which conditions and, therefore, colourcharacteristics of this new variety should be determined with referenceto the observations described herein, rather than from theseillustrations alone.

DETAILED DESCRIPTION

The original variety and progeny have been observed growing in acultivated area in Quebec, Canada. Certain characteristics of thisvariety, such as growth and colour, may change with changingenvironmental conditions (e.g., light, temperature, moisture, nutrientavailability, or other factors). Colour descriptions and otherterminology are used in accordance with their ordinary dictionarydescriptions, unless the context clearly indicates otherwise. Colourdesignations are made with reference to the Royal Horticultural Society(R.H.S.) Colour Chart. All colour characteristics were determined usingthe 1986 version of the Royal Horticultural Society (R.H.S.) colourcharts and measured characteristics were based on ten plan measurements.It should be understood that the colours may vary, depending on factorssuch as growing and lighting conditions.

The comparative tests and trials for ‘Emily Carr’ were conducted inMorden, Manitoba. The plants were placed in groups of 3 with a plantspacing of 3 feet and row spacing of 7 feet. Evaluations were made over7 years. The plants used in the assessment of the characteristics wereplanted in 1996 (long beds) and 1991 (NTA) and had reached maturestature when assessed in 2005 and again on Jun. 30, 2008 and on Jul. 11,2008.

‘Emily Carr’ can be distinguished from its parents by the following:

-   -   The female parent, ‘Cardinette’ (unpatented) derived selection        is a less hardy selection. ‘Emily Carr’ is more vigorous;    -   Compared to its male parent, ‘Cuthbert Grant’ (unpatented),        ‘Emily Carr’ is redder in color, is more up-right and has        slightly smaller flowers.

The ‘Emily Carr’ rose was compared to the ‘Champlain’ (unpatented)variety, referred to as the “reference variety.” For comparison, severalphysical characteristics of the rose variety ‘Champlain’ (unpatented)are compared in Chart 1.
